  • GALVANIC BATTERY This invention relates to galvanic batteries.
  • galvanic batteries e.g. flashlight batteries, consisting of alkaline manganese dioxide-zinc cells, wherein each cell, includes a plastic casing with current collectors which accommodates a manganese dioxide cathode, a separator disposed on one side of the cathode, and a zinc pressed-powder anode.
  • galvanic batteries show a marked decrease in capacity under high drain conditions.
  • Another disadvantage of such galvanic batteries is that the electrolyte and carbonates tend to leak to the battery surface during long-term storage and discharge of the batteries.
  • a galvanic battery e.g. a flashlight battery, consisting of alkaline manganese dioxide-zinc cells, wherein each cell includes a plastic casing with current collectors which accommodates a cathode, two diaphragms disposed on both sides of the cathode, and two zinc powder anodes separated from the cathode by the diaphragms, the cell casing being made in the form of two shells within which the three electrodes are disposed.

  • each shell has provision on its edge periphery for an extension for insulating the negative and the positive current collectors from each other by forming a lap joint from the edge extensions of both shells when assembling the cell.
  • a bank of assembled cells are housed in a hermetic plastic bag to be contained within a cellulosic outer casing.
  • the electrodes surface areas are twice as great as that of the known batteries and the discharge current will be correspondingly higher.
